Definitions

  • the present invention relates to a vice for securing a variety of flat wrenches and to its use for creating or copying the teeth of their bit.
  • the present invention provides a universal vice for flat keys comprising a lower plate and an upper plate, the peripheral part of the opposite bases collaborates in the manner of jaws to clamp a longitudinal part of a bit of flat keys while leaving the other longitudinal part of the bit accessible, characterized in that said opposite bases are hexagonal and in that the shape of said jaws is different on each face of the hexagon, each of said shapes of said jaws being compatible with the section of a particular type of flat key bit.
  • said jaw is for example constituted by a vertical rim under said upper plate and a horizontal extension of said lower plate and adapts to a bit whose tight longitudinal part is of rectangular section.
  • said jaw can also be formed by a vertical point under said upper plate and a notch on said lower plate and adapts to a bit of section in broken lines.
  • said jaw is possibly constituted by a vertical rim under said upper plate comprising a first notch and a second notch identical to the first on said lower plate and adapts to a bit of T-section, the first and the second notches each accommodating a branch of the bar of the T.
  • said jaw is if necessary constituted by a vertical edge under said upper plate whose base admits a profile in an arc of a circle and a recess in an arc of a circle on the lower plate and adapts to a cylindrical bit.
  • a cylindrical shaft passes right through said upper plate and said lower plate, said shaft being made integral at one of its ends with said lower plate by means of a key while at the other of its ends, it screws inside a handle head, a ball crown secured to said upper plate surrounding said shaft between said handle head and said upper plate and a return spring being placed around said shaft between said ball crown and said plate lower inside the recess of the upper plate which receives said shaft, means being further provided for preventing any rotation of the upper plate around the shaft. It is then preferable for said ball crown to include a sleeve occupying part of said recess in the upper plate which receives said shaft and against which said return spring bears, said sleeve being forced into said upper plate.
  • two vices are fixed on a movable plate, one of the vices carrying a blank and the other a key-model of bit with identical sections, a probe coming to detect the shape of the teeth of the key -model so that a cutting tool reproduces this shape on the blank by translation of said plate.
  • each of the two vises is secured to said movable plate by means of a nut screwing around said shaft and fitting into said plate, said nut comprising six notches in the plane of symmetry of each face of said hexagon, one end of a rod passing through said plate being held by elastic means inside one of said notches.
  • the other end of said rod is advantageously external to said plate and has a head to facilitate manual release of said notch when an effort is opposed to said elastic means.
  • the corresponding vice 1 has a cylindrical configuration with a vertical axis. More precisely, it is constituted by a central shaft 300, a lower plate 100 of hexagonal base, an upper plate 200 in the form of a truncated cone with cut sides so that its base admits the same hexagonal surface as that of the lower plate, a ball crown 400 and finally a head 500 in the form of a handle.
  • the bit of a flat key is placed horizontally between the lower plate 100 and the upper plate 200 as indicated in FIG. 2.
  • This top view of the vice specifies in fact how a little less half the width of the bit 22 of a key 2 is pinched between the two plates.
  • the head 23 of the key 2 remains outside the vice as does its toothed part 21.
  • Figure 3 provides a better understanding of the operation of the vice 1.
  • the shaft 300 passes through the two plates as well as the ball ring 400 to come connect by means of an external thread 350 to a nut 510 which extends the head 500 from below handle. It is also made integral with the lower plate 100 by means of a key 130. Between these two points of attachment of the shaft 300, the ball ring 400 and the upper plate 200 are, in turn, free to slide on the shaft 300. It is conceivable, under these conditions, that by screwing the head 500 of the handle, the two plates are tightened towards one another.
  • a return spring 600 is provided. This surrounds the shaft 300 and is supported on the lower plate 100. It is also supported on the base of a sleeve 430 which extends below the ball ring 400. In addition the upper plate 200 is made integral with this sleeve 430 (by force fitting, for example). Thus, as long as it is allowed to expand, the spring tends to move not only the ball ring 400, but also the upper plate 200 from the lower plate 100.
  • the lower plate 100 has for this purpose a mass 110 of material projecting upwards. This has the shape of a parallelepiped off-center with respect to the axis of the vice 1.
  • a recess 210 complementary to this mass 110 is provided in the lower part of the upper plate 200.
  • the mass 110 also fits in the recess 210 over a significant height relative to the travel of the nut 510.
  • the bed of balls 440 which it contains, in fact authorizes the tightening of the head 500 of the handle against the upper part 410 of the crown without efforts of torsion are transmitted at the nesting of the mass 110 projecting from the lower plate 100 and from the recess 210 of the lower part of the upper plate 200.
  • FIG. 4 indicates, using a detail of the section shown in Figure 3, the six bit sections 22 that a vice 1 could for example accommodate.
  • Figure 4-1 it is a very common type flat wrench with a sudden reduction in thickness on side 21 where the teeth are machined. The edge of the face of the corresponding hexagon is then satisfied with simple jaws, for example a vertical flange 220 under the upper plate 200 and a horizontal extension 120 of the lower plate 100.
  • the same form of jaws can be used for cross-shaped shanks (see Figure 4-6) although the vertical distance between the tight plates must be adapted to the thickness of one of the branches of the cross. More complex is the profile of jaws receiving a bit in broken lines (see Figure 4-2).
  • the vertical flange 220 of the upper plate 200 then advantageously comprises a point and the lower plate 100, a notch complementary to the point so that they collaborate to sandwich an angle of the broken line.
  • the two jaws opposite each have a notch intended to accommodate a branch of the upper bar of the T (see Figure 4-3).
  • cylindrical shanks find it advantageous to be pinched between jaws profiled in an arc (see Figure 4-4).
  • new keys made of two plates glued one on the other, one of the plates having an outer rib, can be secured between a flange 220 provided with a recess complementary to the rib and a smooth extension 120 of the plate lower 100 (see Figure 4-5). Many other jaw profiles are obviously possible depending on other types of key not considered here.
  • the vice 1 which has just been described, is advantageously used to reproduce the teeth of a key-model on a blank whose plates are identical. According to Figure 5, this can be achieved by fixing two clamps 1 according to the present invention on a movable plate 3.
  • One of the vices then carries the model key 2m so that it has its toothed part 21 parallel to the edge of the plate 3 within reach of a probe 4.
  • the other vice grips the blank 2c in the same way to expose it to attack by a cutting tool 5.
  • the plate 3 is translated parallel to the bits or perpendicularly so that the cutting tool 5 reproduces the teeth on the blank 2c which becomes thus a copy of the model key 2m.
  • each vice 1 should be properly fixed to the plate 3.
  • Figure 6 shows how this can advantageously be achieved by means of a nut 31 which screws at the base of the shaft 300 of the vice 1.
  • This nut 31 is in fact housed in a recess 32 in the plate 3.
  • a rod 35 is provided for this purpose. This protrudes, on one side, outside the plate 3 and is provided with a head 36 facilitating its handling. To his other end, it has a tip 39 which can penetrate into a notch 33 of the nut 31 and thus block it in the manner of a key.
  • the nut 31 in fact carries six notches placed opposite each face of the hexagon (cf. FIG. 7).
  • the rod 35 also passes through the plate 3 where a complementary cylindrical recess has an enlargement 34 to further accommodate a spring 38 surrounding the rod 35.
  • the spring 38 bears on one side of this enlargement 34 as well as on a ring 37 integral with the rod 35 so that it always tends to hold the point 39 of the rod 35 within the notch 33 of the nut 31.
  • the vice then unlocks from the chosen position by pulling on the head 36. It it is advantageous to provide marks on the vice 1 in order to facilitate its positioning according to the type of wrench to be worked.
